Title (EN) CERAMIC ARTICLE AND PROCESS FOR MAKING THE SAME
(FR) ARTICLE EN CÉRAMIQUE ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN) Disclosed is a process for producing ceramic particles, such as proppants, that have at least 10 percent total porosity. The process includes forming a particle precursor that includes 5 percent to 30 percent of a first ceramic material and at least 40 percent of a second ceramic material. The sintering temperature of the first ceramic material may be lower than the sintering temperature of a second ceramic material. Heating the precursor to a maximum temperature above the sintering temperature of the first material and below the sintering temperature of the second material. Also disclosed is a ceramic article that has a particular combination of chemistry and alumina crystalline phase.
(FR) L'invention porte sur un procédé de fabrication de particules céramiques, telles que des agents de soutènement, qui ont une porosité totale d'au moins 10 pour cent. Le procédé comprend la formation d'un précurseur de particules qui comprend 5 pour cent à 30 pour cent d'un premier matériau céramique et au moins 40 pour cent d'un second matériau céramique. La température de frittage du premier matériau céramique peut être inférieure à la température de frittage d'un second matériau céramique. Le procédé comprend le chauffage du précurseur à une température maximale au-dessus de la température de frittage du premier matériau et au-dessous de la température de frittage du second matériau. L'invention porte également sur un article en céramique qui a une combinaison particulière de chimie et de phase cristalline alumine.
